Which of the following statements about shivering and non-shivering thermogenesis is INCORRECT? Shivering thermogenesis can reach intensities equivalent to 40% of maximum oxygen consumption and involve the oxidation of mainly carbohydrates and lipids. Non-shivering thermogenesis is carried out by brown adipose tissue (BAT). Non-shivering thermogenesis involves involuntary skeletal muscle contraction. Shivering thermogenesis is the process by which the body temperature of hibernating mammals is raised as they emerge from hibernation.
